Agoric Winners of the Gitcoin Cross-Chain Hackathon
The April Gitcoin Virtual Cross-Chain Hackathon ended a week ago, concluding almost a month straight of hacking in collaboration with our cosponsors: Cosmos and Band Protocol. The winners of Agoric’s challenges made good use of our Zoe platform for building reusable smart contracts. Here are details on the projects, and links through to the GitHub for each, plus instructions on how to get started writing smart contracts:
🥇Grand Prize ($1000 in ATOMs)
KryhaDapp — addressed the problem of plastics recyclers not knowing what kind of plastic was used to make bottles and if it was recyclable. Their solution provides a single shared source of truth for tracking product lifecycles. To do this, they used multiple reusable and cooperating contracts (five in all), with a purpose-built UI. (View GitHub) And there’s a video on YouTube with a demo of the Kryha project.
🥈Winners ($500 each in ATOMs)
Time Release — a contract that transfers funds, but only after a specified amount of time has passed. It was notable for being a useful and interesting reusable component with test automation. (View GitHub)
Bonsai Exchange — a fun sales application where users buy bonsais and plant them. It reused an existing component, wired it into a new UI, and interacted with Agoric’s wallet implementation. (View GitHub)
🥉Honorable Mention ($250 each)
Goodwill — a merger of a modified Agoric encouragement dapp with the ultimatum game, a standard economics experiment to measure trust. One person makes an offer on how to divide assets, and another accepts or rejects. Acceptance means the assets are divided per the offer, rejection means both parties get nothing. This project was a start at making re-usable components for quickly building experiments. (View GitHub)
Ice Cave — while incomplete, it made good progress towards integrating Agoric smart contracts with the Phaser gaming framework. The result is a decentralized game with non-fungible loot boxes on top of the Agoric blockchain. (View GitHub)
🛠If you want to learn more about Agoric’s Zoe platform, you might want to read the code and the documentation, and perhaps even install Zoe: npm install @agoric/zoe
